Task 1 Read the text and answer the questions. If we are fond of travelling we see and learn all sorts of things we can never see or learn at home. Though we may read about them in books and newspapers and see pictures of them at the cinema. The best way to study geography is to travel and the best way to get to know and understand the people is to meet them in their own houses. When I was a child every holiday that I had, seemed to be perfect. In those far-off days the sun seemed to shine constantly and the water was always warm. All day I played on the sands with my friends. We made sandcastles with huge yellow walls. Sometimes we left the beach and walked in the country. Although I am now an adult, my idea of a good holiday is the same as it was. I still like the sun and the warm sand and the sound of waves breaking on the beach. I don't want to build sandcastles any longer but still I like sunbathing and the feeling that sand is running through my fingers. I like travelling. And I want to smell different smells I want to see different kinds of trees, flowers and plants. When I spend a holiday in travelling I always take a camera with me and photograph everything that interests or pleases me: the sights of a city, views of mountains, lakes, valleys; the ruins of ancient buildings. Some years later they will remind me the happy time that I had. 1.Why do people like to travel? 2. What did the author do during the vacation? 3. Why does he like travelling? 4.
